I see these values written on inductor symbols on the schematic of an RF filter/PA, what to make of these values?

a) what does "4T1.5D*0.31" means?

b) what does "CM" means in this expression "1uH/CM"?

c) what does "CI" means in this expression "1uH/CI"?

• Impossible to say without more context. They look more like formulas or proportions than values. – duskwuff -inactive- May 24 '16 at 0:20
• Would you believe the second is 1 $\mu$Henry per centimeter? – StainlessSteelRat May 24 '16 at 1:58
